Phytochemical Screening and In vitro Antioxidant Activity of Male and Female Flowers Ethanolic Extracts of Cocos nucifera

Objective: This research is to investigate the phytochemical screening and antioxidant activity of male flowers and female flowers ethanolic extracts of Cocos nucifera. Methods: Antioxidant activity of male and female flowers ethanolic extracts of C. nucifera was evaluated using 2, 2-diphenyl-1-picrylhydrazyl (DPPH•) free radical scavenging activity method. Ascorbic acid 10–50 µg/mL was used as a standard. Results: The C. nucifera male flowers and female flowers ethanolic extract shows the phytochemical actives like alkaloids, carbohydrates, glycosides, tannins and phytosterol, female flowers extract highly present in tannins and phytosterol. Ethanolic extract of male flowers and female flowers was absence of saponins, amino acids, anthraquinones, proteins and terpenes. In the antioxidant activity of the two samples, female flowers extract shows more antioxidant activity than male flowers extracts of DPPH• radical scavenging activity. Conclusion: The extract is reported to contain a range of phytochemical components. In the antioxidant activity of the two samples, female flowers extract shows more antioxidant activity than male flowers extracts of DPPH• radical scavenging activity.
